Abstract

The invention relates to the technical field of ceramic tableware, specifically to surface nitridation ceramic tableware. The surface nitridation ceramic tableware is composed of the following ingredients (by weight): 10-16 parts of illite, 36-40 parts of Xingzi kaolin, 2-4 parts of red copper fiber, 8-12 parts of black mud, 2-4 parts of boron nitride powder having a hexagonal system, 1-2 parts of potassium titanate whisker, 6-10 parts of expanded vermiculite, 1-2 parts of diatomite, 4-6 parts of ceramic polished waste, 4-6 parts of carnallite and 4-6 parts of an auxiliary agent. The tableware has good caking property of the raw materials. As a nitriding layer of 4-8 mm thick is formed on the surface of the tableware, strength and wear resistance of the tableware are greatly enhanced, and the tableware is resistant to collision. Meanwhile, a compact interlayer is formed on the surface of the tableware to avoid oxidization of the tableware and infiltration of pigments into the tableware so as to prevent from damaging beauty of the tableware. Therefore, the tableware has stable performance and is nontoxic.

Description

A kind of surface carburization crockery and its preparation technology
Technical field
The present invention relates to crockery technical field, and in particular to a kind of surface carburization crockery and its preparation technology.
Background technology
With the vessel of potter's clay firing on pottery, with the vessel of china clay firing porcelain.It is ceramic then be pottery, stoneware and porcelain General name.Every potter's clay and china clay both clays of different nature are raw material, through works such as dispensing, molding, drying, roastings Made by skill flow process, implements can be ceramics.
Ceramics development history be Chinese civilization history an important ingredient, China as four major acids ancient country it One, it is that the progress and development of human society is made that remarkable contribution, wherein the invention of ceramics and development are with more unique meaning Justice, on Chinese history, each Chao Gedai has different artistic style and different technical characteristics." china " existing China in English The meaning, the meaning for having ceramics again clearly demonstrate that China is exactly " native places of ceramics ".Porcelain manufacture skill is grasped early in European Before art more than 1,000 years, Han nationality has just produced very exquisite ware.China be in the world earliest using pottery country it One, and Chinese porcelain enjoys the high praise of common people because of its high practicality and artistry.
With the development of modern science technology, many new ceramic kinds are occurred in that in the last hundred years again.They do not use Or the traditional ceramicses raw material such as clay, Anhydrite, quartz is rarely employed, but other special materials are used, or even expand non-silicic acid to Salt, the scope of non-oxidized substance, and occur in that many new techniques.US and European some national documents will " Ceramic " word is interpreted as the common name of various inorganic non-metal solid materials.Therefore the implication of ceramics actually much surpasses More pass by narrow traditional view.
The ceramic industry of China is of long standing and well established, with a long history.Pottery, the raw material used by porcelain are mostly natural inorganic Nonmetallic mineral, these raw materials by processing and refining, cooperation, shaping, high-temperature physics chemical reaction, just formed it is a kind of with original group Into the completely different new material of material, it is ceramics.China's pottery have passed through three phases to porcelain development：Pottery-original pottery Device-porcelain.
As people's living standard is improved, people pursue various exquisite crockery, cooker, but ceramic at present Tableware in cleaning, easily mutually collapse angle and produce gap by collision, and most people is to lose gap tableware to pursue attractive in appearance Abandon, cause to waste very much greatly very much.
The content of the invention
The technical problem to be solved is to provide a kind of surface carburization that intensity is good, abrasion resistance properties are superior pottery Porcelain tableware and its preparation technology.
The technical problem to be solved employs the following technical solutions to realize：
A kind of surface carburization crockery, is made up of the component of following weight portion：Illite 10-16 parts, planetesimal Kaolin 36-40 parts, red copper fiber 2-4 parts, black mud 8-12 parts, hexagonal crystal system boron nitride powder 2-4 parts, potassium titanate crystal whisker 1-2 parts, expansion trematodiasiss Stone 6-10 parts, kieselguhr 1-2 parts, ceramic polished slag 4-6 parts, carnallite 4-6 parts, auxiliary agent 4-6 parts.
The auxiliary agent is made up of the component of following weight portion：Tantalum silicide 1-2 parts, boron nitride 1-2 parts, carborundum 1-2 parts, tungsten Powder 4-8 parts, berberine 0.5-1 parts, camptothecine 0.5-1 parts；Its preparation method is, by tantalum silicide, boron nitride, carborundum, tungsten powder 200-400 mesh fine powders are milled to, then fine powder is stirred in 2000 revs/min of centrifuges, add berberine, happiness while stirring Tree alkali, stirring terminate for 10 minutes, by compound β roentgenizations 30 minutes, compound are placed in 0.01-0.02MPa then close Close in container and process 2 hours, then take out compound and be auxiliary agent.
A kind of preparation technology of surface carburization crockery, comprises the following steps：
(1) illite, planetesimal Kaolin, black mud, expanded vermiculite, kieselguhr, ceramic polished slag, carnallite mixing are ground Into fine powder, fine powder is mixed into into spice and is placed in sealing in glass drying oven, glass drying oven is placed in into exposure 5-7 days under sunlight then；
(2) material drying in glass drying oven is taken out, it is then brilliant with red copper fiber, hexagonal crystal system boron nitride powder, potassium titanate Palpus, auxiliary agent mix and are milled to compound, and the water for being subsequently adding compound weight 35.5%-40.5% mixes into compound thoroughly slurry Material；
(3) tableware of different sizes is made with slurry, tableware -40 DEG C of freezing freezings 30 minutes is put into into, after taking-up With 100-120KHz ultrasound wave to tableware supersound process 5 minutes；
(4) tableware after process is sent in stove and fires, now firing temperature is 400-500 DEG C, will after firing 20 minutes Tableware takes out and is placed in hermetic container and with -40 DEG C of low temperature nitrogens to 1.2-1.6MPa is forced in hermetic container, then pressurize 10 minutes, continue tableware is put in stove and fire, now firing temperature is 700-900 DEG C, after 30 minutes, take out tableware glazing Material, is further continued for firing 1 hour, and now firing temperature is 1200-1300 DEG C, and taking out will in 2 minutes in tableware feeding Air cooler Tableware is air-cooled to room temperature.
The spice includes sodium citrate, carboxylic acid, chlorophyll, water by 1:2:2:The 120 mixed material of ratio.
The invention has the beneficial effects as follows：The each raw material caking property of tableware of the present invention is good, and tableware surface forms 4-8mm thickness nitridings Layer, greatly improves tableware intensity and abrasion resistance properties so that tableware anticollision, while the interlayer that tableware surface forms densification is avoided Tableware oxidation and pigment penetrate into tableware and cause tableware unsightly inside, and tableware is stable in properties, nontoxic.
